What Does SI1 Clarity Diamonds Mean?

SI1 clarity diamonds are Slightly Included to the first degree, meaning inclusions are often found with a regular jeweler’s loupe at 10x magnification. With most diamond shapes, SI1 clarity inclusions are nearly always eye-clean. Meaning you can’t see the imperfections with the naked eye.

In some diamonds, however, you would possibly be ready to notice flaws without magnification. The size, color, and location of the inclusions play into how noticeable they’re. That’s why you would like to review each diamond closely.

Diamond Clarity Grades – a Fast Overview

The GIA—the most important lab grading entity—ranks diamonds on a Clarity scale from best to worst.

The scale is as follows: Flawless (FL), Internally Flawless (IF), Very Very Small Inclusions 1 (VVS1), Very Small Inclusions 2 (VS2), Small Inclusions 1 (SI1), Small Inclusions 2 (SI2), Inclusions 1 (I1), Inclusions 2 (I2), Very Very Small Inclusions 2 (VVS2), Very Small Inclusions 1 (VS1).

The color grade is higher, but everything else is that the same, and it costs over 20% more. And if you’re watching SI1 Clarity Diamonds vs. VVS diamonds, the worth difference is going to be even more significant.
